To all whom/it may concern:

Be it known that I, THOMAS' G. OTfrnRsoN, a citizen of the United States, residing at Woodbury, in the ,county of Gloucester and State of New Jersey, have invented certain 'new and useful Improvements in Preserve- Jar Fastenings, of which the following isa specification, reference being had therein to the accompanying drawings.

Figure l represents a side elevation' of' a' preserve-jar fastening embodying my invention. Fig. 2 represents a vertical section thereof in line x x, Fig. 1. Fig. Brepresents a top or plan view thereof. Fig. 4 -is a perspective view of a modification ofthe yoke and valve. Fig. 5A is an enlarged` detail of the. valve.

Similar letters of reference indicate corresponding parts in the lseveral figures.

My invention consists of a preserve-j ar fastening' formed of a Vclamp or yoke which is adapted to engage with spiral lugs or threadsV on the neck of the jar, and connected centrally to a button ory valve, made of rubber or other soft material, which .is compressed against the lid of the jar and tightly closes a vent therein. Provision is made for permitting the clamp or yoke and button or valve to roll on each other, all as will be hereinafter fully described.

Referring to the drawings, A represents a fruit or preserve jar, and B the lid thereof, the

. latter having a vent, Q, for admission' of air into the jar when the same is to be opened.

D represents aclamp or yoke formed of aI strip of steel or other suitable metal or material, or ofy wire, and having its lends bent downwardly, the terminations thereof being turned inwardly, forming lips E, which are I -adapted to engage with spiral lugs or threads F on the body of the jar; or the clamp or yoke may be made of wire, as shown in Fig'. 4, its ends being suitably bent to engage under the lugs F. On the`under side of the clamp or yoke, at the center thereof, is a button or valve, G, made of rubber or any other suitable material or substance. This is attached securely to the lower end of the pin H, the shank ofo which passes up through a hole in the clamp or yoke, while its upper end is beaded. Thus -the clamp or yoke will freely rotate on the pin and-over the button or valve. This button or valve is in the form Aof a disk.JA On the upper ket, M, between 'the shoulder a on the upper side lol" this button or val ve the construction is I such that should there be any irregularity` in the lid,l gasket, or shoulder of the jar, or the clamp or yoke, button or valve, pin or packing of theffastening, the clamp yoiy'oke and button or valve may, when the 'is being secured upon-.the jar, roll on eachother, avoiding breakage 'or injury to the parts, especially glass; or, if desired, there may be placed a H, and between the button or valve and the h clamp or yoke, which will give the same results in'an equivalent way. l' p The top of the lid has a recess, L, to receive the button or valve G, and the wall around the vent C is slightly raised, so that the button or valve rests thereon, thus avoiding direct contact ofthe body of the button or valve with the lid .and consequentinjury to thev latter when' pressure is appliedto the button or Valve by the action ofthe clamp or yoke. A gaspart. of the jar'and'theunder side of the ends or valve are applied in position the clamp or yoke is rotated, and as it engages with the spiral lugs or threads of the jar and is drawn 1 downwardly it forces the lid firmly on its'seat,

tightly closing 'the jar `and surely retaining the lid in position; The button or valve is also forced by the clamp or yoke against the wall of the vent, so that the vent is reliably closed.- The button or valve does not rotate with the clamp, but remains xed on the lid,

thus avoiding any liability toinjure 'the' lid, ,9o

especially around the wall 'of the. vent. The upper side of the valve being plane, it is adapted to rest against the yoke or clamp and permit it to rotate easily thereon while the lid is being fastened to the jar.

. 9 In -order to open the jar, the clamp or yoke D 6o chipping of the center ofthe lid when made of 4 of the lid, is employed, and when thelidand Athe clamp' or yoke with itsconnected button 8s lid and compressed on the same around the is properly rotated or unscrewed, :the button or valve being raised therewith; thereby uncovering the vent C land permitting airjto enterthejar.

Having thus described my invention, what I claim as new, and desire to'secure by Letters Patent,'iis- 1. Aijar having roo spiral lugs and a ,lid havl i ing a vent and a recess in its upper face, in combination with a button or valve, pin, and

clamp or yoke, said button or valve resting in nation with the lid B, having vent C and recess L, button or valve G, clamp or yoke D, having lips E, and pin H, pivoted to said clamp, substantially as and for the purpose set forth 3. The jar A, having spiral lugs, in combination with the lid B, having vent C .and recess L, clamp or yoke D, having lips E, button f -or valve G, resting in recess L, and gasket-M and pin H, pivoted to said clamp', substantially as described.

- presence of two witnesses.

4. In a preserve-jar fastening, the oombination Vof the following elements, viz: a lid oen- 2o trally perforated, a clamp or yoke having bent. ends for engaging under the spiral lugs of the jar, a valve pivoted centrally in and t0 the clamp or yoke by means of a headed pin,A the upper side of the valve being plane and arranged to rest against the clamp or yoke and permit it to rotateeasily thereon while the lid is being fastened onthe jar, substantially as. described.
